CURTAIN-FIXTURE.

Specification of Letters Patent No. 31,550, dated February 26, 1861.

To all whom it may concern.'

Be it known that I, JOSEPH Y. MARSH, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Curtain- Fixtures; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein- Figure l, is a vertical section of the ends of the curtain roller and fixtures, Fig. 2, is a side view of the spring barrel, and F ig.r3,

is a side view of the stop lever and grooved pulley.

Similar marks of reference denote the same parts.

Spring curtain fixtures have heretofore been made in which a flat or lvolute spring has been applied, and a ratchet wheel and lever have been employed to stop the curtain at any given point.

The nature of my said invention consists in a grooved pulley and pointed lever that act to stop the curtain at any given point or upon being released allow the said curtain to be wound up by a volute spring. By using this grooved pulley and pointed lever the noise consequent upon the use of' a ratchet and pawl are avoided, and the curtain can be controlled as it is rolled up by the spring by a slight friction from said lever instead of being rapidly wound up and sometimes injured by the uncontrolled movement ofthe spring.

The spring barrel and the grooved pulley are connected to the respective ends of the curtain roller by means of projecting squares entering metallic ends upon the wooden roller, whereby the end pieces or brackets, carrying the spring and pulley, can be tted up permanently and then the roller sawed off to length andintroduced with its metallic ends (upon slightly loosening the screws of one bracket) thereby a large amount of the trouble consequent upon fitting up spring curtains particularly in coaches and carriages is avoided.

In the drawing a, is a roller of 'wood receiving the curtain b, in any usual manner, c, c, are the metallic ends of the same with square holes in the center taking the squared projecting ends of the axes d, e. The axis d, is in the spring box f, in which is the volute spring g, and said box f also forms the bracket in consequence of the iiange l, that is adapted t take the casing or other part to which it is to be attached by screws or otherwise. The cap 2, of this spring box next the roller a, is removed in Fig. 2. One end of the spring g is connected to the axis d, the other to the box f, so that the act of drawing down the curtain winds up said spring. The box L, at the other end of the rollera, is similarly connected to the casing by the flange l, and provided with a cap 2, corresponding to the spring box. e, receives the grooved pulley z', and c, is a lever set on a fulcrum formed by a notch taking the rim of the box h, and the inner end of said lever is pointed as shown to take the grooved roller or pulley z', and block or stop the same; 3, is a spring to press the point of the lever to the Agroove of the pulley. The outer end of the lever may be provided with a cord, by which the point may be raised or relieved from the grooved pulley so that the spring g can wind up the curtain. It will be evident that the pulley z' might be formed as a single beveled edge and the lever lc, as a fork to set over the same, thereby reversingthe shape of the parts, without altering their action.

Having thus described my said invention what I claim and desire to secure by Letters Patent is The pulley z', and pointed lever 7e, applied in combination with a spring blind or curtain roller substantially as and for the purposes specified.

In witness whereof I have hereunto 'set my signature this thirty first day of J anuary 1861.
